Petunia plant named ‘Sunsurf Depausa’

ABSTRACT

A new and distinct cultivar of  Petunia  plant named ‘Sunsurf Depausa’, characterized by its compact, mounding and trailing plant habit; vigorous growth habit; freely branching habit; early and freely flowering habit; long flowering period; medium-sized dark red purple-colored flowers; and good garden performance.

Botanical designation: Petunia×hybrida.

Cultivar denomination: ‘SUNSURF DEPAUSA’.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Petunia plant, botanically known as Petunia×hybrida and hereinafter referred to by the name ‘Sunsurf Depausa’.

The new Petunia plant is a product of a planned breeding program conducted by the Inventor in Higashiomi, Shiga, Japan. The objective of the breeding program is to create new compact freely branching and freely flowering Petunia plants with mounding habit and attractive flower coloration.

The new Petunia plant originated from a cross-pollination made by the Inventor in March, 2008 in Higashiomi, Shiga, Japan of a proprietary selection of Petunia×hybrida identified as code name BW1, not patented, as the female, or seed, parent with a proprietary selection of Petunia×hybrida identified as code name PF411-5, not patented, as the male, or pollen, parent. The new Petunia plant was discovered and selected by the Inventor as a single flowering plant within the progeny of the stated cross-pollination in a controlled environment in Higashiomi, Shiga, Japan in October, 2008.

Asexual reproduction of the new Petunia plant by terminal cuttings in a controlled environment in Higashiomi, Shiga, Japan since October, 2008 has shown that the unique features of this new Petunia plant are stable and reproduced true to type in successive generations.

SUMMARY OF THE INVENTION

Plants of the new Petunia have not been observed under all possible environmental conditions and cultural conditions. The phenotype may vary somewhat with variations in environmental conditions such as temperature and light intensity without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Sunsurf Depausa’. These characteristics in combination distinguish ‘Sunsurf Depausa’ as a new and distinct Petunia plant:

-   -   1. Compact, mounding and trailing plant habit.     -   2. Vigorous growth habit.     -   3. Freely branching habit.     -   4. Early and freely flowering habit.     -   5. Long flowering period.     -   6. Medium-sized dark red purple-colored flowers.     -   7. Good garden performance.

Plants of the new Petunia can be compared to plants of the female parent selection. Plants of the new Petunia differ primarily from plants of the female parent selection in plant habit as plants of the new Petunia are more trailing than and are not as upright as plants of the female parent selection. In addition, plants of the new Petunia have larger flowers than plants of the female parent selection.

Plants of the new Petunia can be compared to plants of the male parent selection. Plants of the new Petunia differ primarily from plants of the male parent selection in flower color as plants of the male parent selection have red-colored flowers. In addition, plants of the new Petunia have smaller flowers than plants of the male parent selection.

Plants of the new Petunia can also be compared to plants of the Petunia ‘Sunpurple’, disclosed in U.S. Plant Pat. No. 16,358. In side-by-side comparisons conducted in Higashiomi, Shiga, Japan, plants of the new Petunia and ‘Sunpurple’ differed primarily in the following characteristics:

-   -   1. Plants of the new Petunia were larger than plants of         ‘Sunpurple’.     -   2. Plants of the new Petunia had smaller leaves than plants of         ‘Sunpurple’.     -   3. Plants of the new Petunia had smaller flowers than plants of         ‘Sunpurple’.     -   4. Plants of the new Petunia and ‘Sunpurple’ differed in flower         color as plants of ‘Sunpurple’ had lighter red purple-colored         flowers.
